How To Install Inellij On Linux – IDE Installation Linux Methods

by

Setting up IntelliJ on Linux begins with downloading the tarball from JetBrains’ official website and extracting it. If you are wondering how to install inellij on linux, you have come to the right place. This guide walks you through every step, from system preparation to launching your first project, with clear instructions and practical tips.

IntelliJ IDEA is one of the most powerful IDEs for Java and other JVM languages. Linux users often prefer it for its speed and flexibility. The installation process is straightforward, but there are a few details to get right. Let us start with the basics.

Prerequisites For Installing IntelliJ On Linux

Before you begin, ensure your system meets the minimum requirements. IntelliJ IDEA runs on most modern Linux distributions, including Ubuntu, Fedora, and Debian.

  • A 64-bit processor with at least 2 GB RAM (4 GB recommended)
  • Java Development Kit (JDK) version 8 or higher
  • At least 2.5 GB of free disk space for the IDE and projects
  • An active internet connection for downloading files

Check your current Java version by running java -version in the terminal. If Java is not installed, you can install OpenJDK using your package manager. For example, on Ubuntu, run sudo apt update && sudo apt install default-jdk.

How To Install Inellij On Linux

This section covers the exact steps for installing IntelliJ IDEA on Linux. Follow them carefully to avoid common pitfalls.

Step 1: Download The IntelliJ Tarball

Visit the official JetBrains website at jetbrains.com/idea/download. Choose the edition you need: Community (free) or Ultimate (paid). Click the Linux tab and download the .tar.gz file.

The download may take a few minutes depending on your internet speed. The file size is around 600 MB for the Community edition and 1 GB for Ultimate.

Step 2: Extract The Archive

Open a terminal and navigate to the directory where you saved the tarball. Usually, this is the Downloads folder. Run the following command to extract it:

tar -xzf ideaIC-2023.3.tar.gz

Replace ideaIC-2023.3.tar.gz with the actual filename you downloaded. The extraction creates a folder named something like idea-IC-233.11799.241.

Step 3: Move IntelliJ To A Suitable Location

For system-wide access, move the extracted folder to /opt. Use the command:

sudo mv idea-IC-233.11799.241 /opt/idea

This places IntelliJ in a standard location. You can also keep it in your home directory if you prefer, but moving it to /opt makes it easier for all users.

Step 4: Create A Desktop Entry

To launch IntelliJ from your application menu, create a desktop entry file. Run:

sudo nano /usr/share/applications/idea.desktop

Paste the following content:

[Desktop Entry]
Name=IntelliJ IDEA
Comment=IntelliJ IDEA IDE
Exec=/opt/idea/bin/idea.sh
Icon=/opt/idea/bin/idea.png
Terminal=false
Type=Application
Categories=Development;IDE;

Save the file and exit. Now you can find IntelliJ in your applications menu.

Step 5: Launch IntelliJ For The First Time

You can start IntelliJ from the terminal by running /opt/idea/bin/idea.sh or by clicking its icon in the menu. The first launch will prompt you to import settings from a previous installation. Choose “Do not import settings” if this is a fresh install.

Follow the setup wizard to select your UI theme, keymap, and plugins. The wizard also lets you install additional plugins for languages like Python, Go, or JavaScript.

Alternative Installation Methods

Besides the manual tarball method, there are other ways to install IntelliJ on Linux. Each has its pros and cons.

Using Snap Package

Snap is available on many Linux distributions. To install IntelliJ via Snap, run:

sudo snap install intellij-idea-community --classic

For the Ultimate edition, use intellij-idea-ultimate. Snap packages update automatically, which is convenient. However, they may have slower startup times.

Using Flatpak

Flatpak is another package format. Install it with:

flatpak install flathub com.jetbrains.IntelliJ-IDEA-Community

Flatpak versions are sandboxed, which improves security but may limit file system access. You can grant permissions using Flatpak commands.

Using JetBrains Toolbox

JetBrains Toolbox is a desktop application that manages multiple JetBrains IDEs. Download the Toolbox App from the JetBrains website, extract it, and run the jetbrains-toolbox executable. From there, you can install IntelliJ and other tools with one click.

Toolbox also handles updates and version management automatically. It is the recommended method for users who work with multiple JetBrains products.

Configuring IntelliJ After Installation

Once installed, you may want to customize IntelliJ for your workflow. Here are some essential configurations.

Setting The JDK

IntelliJ needs a JDK to compile and run Java code. Go to File > Project Structure > SDKs and add your JDK path. If you installed OpenJDK, the path is usually /usr/lib/jvm/java-11-openjdk-amd64.

You can also download a JDK directly from within IntelliJ using the Download JDK button.

Installing Plugins

Plugins extend IntelliJ’s functionality. Open File > Settings > Plugins and browse the marketplace. Popular plugins include:

  • Lombok for reducing boilerplate code
  • Rainbow Brackets for better code readability
  • Git Integration for version control
  • Docker for container management

Install plugins by clicking the Install button next to each one. Restart IntelliJ if prompted.

Adjusting Memory Settings

If you work with large projects, increase the IDE’s memory allocation. Edit the idea.vmoptions file located in the IntelliJ configuration directory. For example, add:

-Xms512m
-Xmx2048m

This sets the initial heap size to 512 MB and the maximum to 2 GB. Save the file and restart IntelliJ.

Common Installation Issues And Fixes

Even with careful steps, you might encounter problems. Here are solutions to frequent issues.

IntelliJ Does Not Launch

If clicking the icon does nothing, try launching from the terminal to see error messages. Run /opt/idea/bin/idea.sh and check the output. Common causes include missing Java or permission errors.

Ensure the idea.sh file has execute permissions. Run sudo chmod +x /opt/idea/bin/idea.sh if needed.

No JDK Found

IntelliJ may complain about a missing JDK even if you have one installed. Set the JAVA_HOME environment variable in your .bashrc or .zshrc file:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH

Reload the file with source ~/.bashrc and restart IntelliJ.

Desktop Icon Not Appearing

If the icon does not show up in your application menu, check the desktop entry file for errors. Ensure the Exec and Icon paths are correct. You may need to log out and log back in for changes to take effect.

Uninstalling IntelliJ From Linux

If you need to remove IntelliJ, the process depends on how you installed it.

Removing Tarball Installation

Delete the installation folder and the desktop entry file:

sudo rm -rf /opt/idea
sudo rm /usr/share/applications/idea.desktop

Also remove the configuration directory in your home folder: rm -rf ~/.config/JetBrains. This deletes all settings and caches.

Removing Snap Or Flatpak

For Snap, run sudo snap remove intellij-idea-community. For Flatpak, use flatpak uninstall com.jetbrains.IntelliJ-IDEA-Community.

Removing Toolbox Installation

Delete the Toolbox App folder and the IntelliJ installation directory. Toolbox stores IDEs in ~/.local/share/JetBrains/Toolbox/apps. Remove that folder to free up space.

Frequently Asked Questions

Here are answers to common questions about installing IntelliJ on Linux.

Can I install IntelliJ on Linux without root access?

Yes, you can extract the tarball to your home directory and run the idea.sh script directly. You will not have a desktop entry, but the IDE will work fine.

Which edition should I choose, Community or Ultimate?

The Community edition is free and supports Java, Kotlin, and a few other languages. The Ultimate edition adds support for Python, JavaScript, SQL, and more. Choose based on your development needs.
